Allwinner A733 octa-core Cortex-A76/A55 AI SoC supports up to 16GB RAM for Android 15 tablets and laptops

Allwinner A733 is an octa-core Cortex-A76/A55 processor with an optional 3 TOPS NPU and support for up to 16GB RAM designed for Android 15 tablets and laptops such as the Teclast P50Ai with a 10.92-inch touchscreen display. With two Cortex-A76 cores, six Cortex-A75 cores, an Imagination BXM-4-64 MC1 GPU, and an NPU, the Allwinner A733 looks very similar to the Allwinner A736 we noted in a roadmap last year. But there’s no news about the A736, so maybe the name was dropped and the Allwinner A733 was launched instead. Allwinner A733 specifications: CPU Dual-core Arm Cortex-A76 @ up to 2.00 GHz Hexa-core Arm Cortex-A55 @ up to 1.79 GHz Single-core RISC-V E902 real-time core GPU – Imagination Technologies BXM-4-64 MC1 VPU 8Kp24 H.265/VP9/AVS2 decoding (no mention of AV1) 4Kp30 H.265/H.264 encoding AI accelerator – Optional 3 TOPS NPU Memory 192 KB SRAM + 512 KB shared SRAM 32-bit LPDDR4/LPDDR4x/LPDDR5 interface […]

NXP i.MX 94 octa-core Cortex-A55/M33/M7 processor targets Edge AI industrial and automotive applications

NXP i.MX 94 is an octa-core Arm SoC with up to four Cortex-A55 application cores, two Arm Cortex-M33 real-time/functional safety cores, two Arm Cortex-M7 real-time/functional safety cores, and an NXP eIQ Neutron NPU designed for Edge AI industrial and automotive applications I initially thought it would be a cost-down version of the NXP i.MX 95, and while it shares many of the same features, it’s more an application-specific processor designed specifically for industrial and automotive applications, lacking a 3D GPU, camera input interfaces, a MIPI DSI display interface, and 10GbE networking, but increasing the number of real-time cores (at the cost of application cores) and adding several networking features such as an Ethernet time-sensitive networking (TSN) switch, 2.5GbE interface, an Ethercat controller, and support for industrial protocols like Profinet or OPC-UA FX. NXP i.MX 94 specifications: CPU Up to 4x Arm Cortex-A55 cores 2x Arm Corex-M7 cores, one for functional […]

Allwinner A523 octa-core Cortex-A55 processor to show up in tablets, SBCs

Allwinner A523 is an octa-core Cortex-A55 processor clocked at up to 1.4/1.8GHz in big.LITTLE (DynamIQ) configuration and mainly designed for tablets with multiple display interfaces such as two 4-lane MIPI DSPI interfaces, two MIPI CSI camera interfaces, a Mali-G57 GPU, and more. But the block diagram below also shows two Gigabit Ethernet (GMAC) interfaces and HDMI 2.0 output among other interfaces meaning it will likely be used in Smart Home products as the Allwinner R828/MR828, and possibly automotive products as the Allwinner T527. I first discovered the Allwinner A523 last March via a tweet by 柚木鉉 (GLGH_), but there was little information at that time. We now have further details about the processor and upcoming products such as the Teclast P26T, and a potential Allwinner A523 single board computer or module. Allwinner A523 preliminary specifications: CPU Application – Octa-core Arm Cortex-A55 @ in big.LITTLE configuration with four cores @ […]

NXP i.MX 93 processor combines Cortex-A55 cores with Ethos U65 microNPU

NXP has unveiled the i.MX 93 processor family comprised of i.MX 935x, 933x, 932x, and 931x parts at this time with up to two Cortex-A55 cores, one Arm Cortex-M33 real-time core, as well as an Ethos U65 microNPU for machine learning (ML). We wrote about i.MX 9 family back in March with NXP telling us it would include an Arm Ethos U-65 microNPU and EdgeLock secure enclave, be manufactured with a 16/12nm FinFET class process, and includes the “Energy Flex” architecture to optimize power consumption by turning on/off specific blocks in the processor. The NXP i.MX 93 is the first family leveraging those new features, and we know have some more details. NXP i.MX 93 processor specifications: CPU 1x or 2x Arm Cortex-A55 @ 1.7 GHz with 32KB I-cache, 32KB D-cache, 64KB L2 cache, 256KB L3 cache with ECC 1x Arm Cortex-M33 @ 250 MHz low power microcontroller with 256KB […]

Renesas RZ/G2L MPUs Feature Cortex-A55 & Cortex-M33 Cores for AI Applications

Renesas Electronics Corporation announced RZ/G2L MPUs, allowing enhanced processing for an extensive variety of AI applications. The RZ/G2L group of 64-bit MPUs includes three new MPU models featuring Arm Cortex-A55, and an optional Cortex-M33 core. These are RZ/G2L, RZ/G2LC, and RZ/G2UL MPUs. The Cortex-A55 CPU core typically delivers approximately 20 percent improved processing performance compared with the previous Cortex-A53 core, and according to Renesas, is around six times faster in “essential processing for AI applications”. The company already has four mid to high-end design level MPUs including RZ/G2E, RZ/G2N, RZ/G2M, and RZ/G2H, with combinations of Cortex-A53 and Cortex-A57 cores. The new RZ/G2L group of three MPUs forms the entry-level design with Cortex-A55. Hence, the seven MPU models together provide scalability from entry-level to high-end design. Common Key Features in RZ/G2L, RZ/G2LC, and RZ/G2UL MPUs Up to 2x Cortex-A55 cores Cortex-M33 core Camera interface (MIPI-CSI) Display interface (Parallel-IF) USB 2.0 interface […]

Amlogic S905X3 vs S905X4 – Features Comparisons

AV1 capable Amlogic S905X4 processor has been expected for more than a year, and only now are we starting to see announcements of S905X4 TV boxes and development kits. So it may be a good time to compare the features of the new Amlogic S905X4 processor again its predecessor, namely S905X3, and see if there are other notable differences apart from support for AV1 open video codec. We’ll use data from S905X3 specifications, S905X2 vs S905X3 comparison, and a post on SDMC LinkedIn page. Amlogic S905X4 will be slightly faster due to the higher (default) maximum CPU frequency of 2.0 GHz, but most people will not notice the difference. S905X4 is supposed to support Vulkan 1.1, while S905X3 does not, but I believe this is just due to more up-to-date Android SDK, and not differences in the silicon itself. S905X4 supports Nagra DRM, a more recent version of HDCP, and […]

Rockchip RK3566 and RK3568 datasheets and features comparison

We first covered Rockchip RK3566 processor in February, but we’ve been informed the specifications have changed since then, and earlier this month, we also wrote about RK3568 quad-core Cortex-A55 processor with the same base features but some extra I/Os. But due to NDAs, people familiar with the chips could not release too many details, so we did not get the full picture. This has just changed as the datasheets for both processors have just dropped from somewhere here and there, and we can get a much closer look. RK3566 and RK3568 specifications I’ve highlighted the obvious differences above, with the big ones being the PCIe interface and RK3568 having dual Gigabit Ethernet. The other features comparison can be found in the table below. Multiplexed interfaces. Important note. Rockchip RK3566 and RK3568 are using Multi-PHY Interfaces, and while the table above lists all possible interfaces, they can not all be used […]

Rockchip RK3568 processor to power edge computing and NVR applications

We recently reported on the Rockchip developer conference (RKDC) 2020, and especially the upcoming Rockchip RK3588 Cortex-A76/A55 processor that packs a lot of power and features, and is now scheduled to launch in Q3 2021. But as you can imagine there were other products revealed during the conference, including the new Rockchip RK3568, similar to the previously announced RK3566, and designed for edge computing and network video recorder (NVR) applications. There’s also an RK353X processor specifically designed for NVR application that should have similar performance as RK3568, but a lower cost, as well as two UP camera SoC with RV1106 and RV1128. CNX Software managed to obtain the presentation for the RK3568 processor from the conference so we’ll focus on the quad-core Cortex-A55 processor in this post. Rockchip RK3568 specifications: CPU – Quad-core Cortex-A55 processor with NEON and FPU GPU – Mali-G52 EE with support for OpenGL ES 1.1 to […]
